sh: cpufreq: notify about rate rounding fallback. (1a565cf0) · Commits · 戴 / test

The general case for platforms that support the clock framework fully will be rate table rounding, while others will have to fall back on much coarser general rate rounding. Notify about it during boot so the limited functionality for the given subtype is appropriately noted. Signed-off-by:
